摘要:
无柱大跨地铁车站具有美观、方便、实用等优势,由于其结构形式取消了中柱,其抗震性能的可靠性也因此备受关注.为研究无柱大跨地铁车站在多种工况下的地震反应,本文以南宁某无柱支撑地下地铁车站为工程背景,对模型结构的相似比、模型材料进行相关的设计并选用地震波El-Centro波、Taft波、南宁人工波,开展了现浇式无柱变截面地铁车站模型的振动台试验研究.基于动力模型试验建立了有限元模型,分析了结构在地震波作用下的振动响应.最终研究成果表明:应力集中大多出现在结构的底、顶板和侧墙连接部位以及中板两侧靠近板墙的连接处,建议在工程应用中针对这些结构部位采取合理措施进行局部加强.
Abstract:
The pillarless large-span subway station has the advantages of being beautiful, convenient and practical. Due to the elimination of the center column in its structural form, the reliability of its seismic performance has also received much attention. In order to study the seismic response of the pillarless large-span subway station under various conditions, a pillarless-supported underground subway station in Xi'an is chosen as the engineering background. The similarity ratio of model structure and model materials were designed. The shaking table experiment was carried out, considering El-Centro wave, Taft wave, and Xi'an artificial wave. Based on the dynamic model test, the finite element analysis of the structure was made to study the vibration response of the structure under seismic waves. Results show that the stress concentration of the structure appears at the joints of the bottom of the station, at the roof and the side wall and the joints of the two sides of the middle plate near the wall. It is recommended to take reasonable measures for local strengthening of these structural parts in engineering applications.
